Technical Specifications and Features

This vented disc brake rotor features a nominal thickness of 1.417 inches (36.000 mm) and a discard thickness of 1.339 inches (34.000 mm), ensuring safe replacement intervals. The rotor’s overall height measures 1.890 inches (48.000 mm), and it has an outside diameter of 14.961 inches (380.000 mm). The floating disc mounting system and smooth surface finish contribute to even pad wear and reliable stopping power. The rotor includes five mounting holes with a bolt circle diameter of 108.000 mm and stud/lug hole diameter of 0.555 inches (14.100 mm), matching the factory specifications for Jaguar F-Type, XF, XFR, XFR-S, XJ, XJR, XJR575, XKR, and XKR-S models.

Applications and Problem Solving

• Replacement for worn or warped rotors on Jaguar F-Type and XKR models
• Improves braking consistency by reducing heat-related fade
• Prevents corrosion damage in humid or salty environments
• Restores proper rotor thickness for safe braking performance
• Addresses vibration or noise caused by uneven rotor surfaces

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 1.339 inches (34.000 mm) before installation. Clean the hub surface to prevent runout and ensure proper rotor seating. Use the correct torque specifications for the five mounting bolts on the 108.000 mm bolt circle. This rotor does not include bearings or ABS tone rings, so verify compatibility with your vehicle’s existing components. Proper bedding-in of brake pads after installation is recommended for optimal performance.
